When is it appropriate to begin a new paragraph

The answer will vary. If you're in elementary, then after 4-6 sentences. Middle school, you would write 6-8 sentences. If you're in high school, then 8-15 sentences would be appropriate to begin a new paragraph. Teachers always appreciate more work. Hope I helped :).   

You should start a new paragraph when your subject or topic changes.

Delegates: representatives who cast votes at a political party's national convention. binding: if a primary or caucus is “binding” that means the delegates won in that contest are legally bound to vote for a particular candidate at the parties national convention.a primary is a preliminary election used to determine a party's nominee for a specific office. the winner of the party's caucus, or primary, wins the party nomination for that state. then the delegates meet at their party's national party convention, which is a formal gathering of all party delegates from all states.
